The Health Ministry on Monday launched a monthlong “Two Drop” campaign of
attenuated oral polio vaccine (OPV) for children from age four months through
9.5 years in well-baby (tipat halav) centers in the south of the
Ninety-eight percent of the population has already received
injected killed polio virus vaccine (IPV).
The aim is to wipe out the
wild polio virus in the sewage in the area that has turned some two dozen people
– mostly children – into healthy carriers of the virus and threatens to infect
the small minority who had not previously received the IPV.

The ministry came under pressure from the World Health
Organization, which six weeks ago sent three experts here to learn how the virus
– which apparently arrived from Egypt or elsewhere in Africa – got into the
sewage; the foreign experts worried that it could spread
Although the ministry has said the hundreds of thousands of
imported doses of OPV are safe, officials hesitated for weeks to give it to
young children who have already been vaccinated with IPV at the age of two
months, four months, six months, 12 months and in second grade.
campaign, due to cost several million shekels, comes at a time when families are
on vacation throughout Israel and abroad and children are out of classrooms. For
the campaign to succeed, parents have to take their children to tipat halav
clinics for the painless vaccination.
Until the end of 2008, the ministry
routinely gave children OPV in addition to IPV, but it stopped this under the
advice of the WHO, which thought it was no longer necessary.
The new OPV
formula, with two rather than three strains, is even less likely to cause the
paralytic disease – an extremely rare complication – than the previous

Nearly 25 years ago, a number of cases of the paralytic
disease in adults and children led to a similar OPV campaign among all adults
under the age of 40 throughout the country.
The IPV shot protects the
individual who received it; the OPV drops enter the gastroenterological system
and protect those who have not received the shot, via contact with
Adults – parents, caregivers and nursery school teachers – are
asked to observe good hygienic practices by washing hands with soap and water
after changing diapers and before touching food.
Since the first evidence
of wild polio virus was found randomly in sewage in the South in February, the
ministry has been checking stool samples and testing sewage samples in the South
and in other parts of the country.
Giving IPV to children in the area who
had not previously been vaccinated did not succeed in completely wiping out the
The virus enters the body via the mouth and is eliminated in the
stools. Only one person out of 1,000 who has not been vaccinated by IPV will
contract the paralytic disease.
If the child is due to get the OPV but
has a fever, the parent should wait to take him to the tipat halav clinic. It
should also not be given if the child has a first-degree relative with a weak

OPV from the school nurse. If residents of the Center or the North are staying
in the South for a minimum of a week, children up to the age of nine should
receive the drops, the ministry said. Children born before 2004 will not be
vaccinated with OPV. Neither is there a need to give drops to tourists.
